[catalogued under 10. Modality / E. Possible worlds / 1. Possible Worlds / e. Against possible worlds]

Full Idea

Each possible worlds model contains a set of possible worlds. For this reason, possible worlds semantics is often charged with smuggling in heavy metaphysical commitments.

Gist of Idea

Possible worlds models contain sets of possible worlds; this is a large metaphysical commitment

A Reaction

To a beginner it looks very odd that you should try to explain possibility by constructing a model of it in terms of 'possible' worlds.
